Description Gerald Teschl 2000-12-21 15:20:20 UTC
yppasswd creates DES encrypted passwords even if md5 is set and even if
the old password was md5.

Comment 2 Gerald Teschl 2001-01-17 18:47:17 UTC
Since the ordinary passwd does it right I recommend to remove yppasswd and
replace it
by a link to passwd.

I think passwd may be broken actually. I think it looks at the local
configuration and uses md5 if it is used there. setting an md5 password on the
nis server may break login from non-md5 capable machines.

I agree that we should set a md5 password if the previous one is md5 though.

Comment 5 Alexander Larsson 2002-03-25 16:19:42 UTC
yp-tools-2.6-4 sets a MD5 password if the old one was MD5. This is the best we
can do I think.

Comment 6 Doug Sibley 2003-09-15 12:52:53 UTC
When I try to add a new already crypted password in MD5 format $1$<salt>$<hash>
via useradd -p I get a blank entry in my nis shadow table. Certianly this is an
easy enough to fix bug.
